Authorities are reviewing the shooting of Wilmington area teenager shot and killed Sunday by a police officer who responding to a call for help from the mentally ill teen’s family.

Keith Vidal, 18, was armed with a small screwdriver but family members have told Wilmington media other responding officers were successfully calming the youth down when a third officer arrived on the scene, according to what Vidal’s family told reporters from WECT in Wilmington.

[Mark] Wilsey said officers had his son down on the ground after the teen was tased a few times and an officer said, “we don’t have time for this.” That’s when Wilsey says the officer shot in between the officers holding the teen down, killing his son.

“There was no reason to shoot this kid,” Wilsey said. “They killed my son in cold blood. We called for help and they killed my son.”

A Southport Police Department detective, Byron Vassey, has been put on administrative leave in connection with the incident, Wilmington TV station WECT reported. Authorities have not said if Vassey was the shooter, but no other officers from the other police departments on the scene have been placed on leave.

The State Bureau of Investigation is investigating the shooting.

The TV station also reviewed 911 documents that indicated the officer who shot the teen had arrived at the family’s home seconds before the shooting.

Vidal was a senior at South Brunswick High School and scheduled to graduate this spring, according to the Wilmington Star-News article about the shooting.

The national blog, ThinkProgress, has also picked up on shooting, and published a post today about the incident.

During Sunday’s incident, Vidal had apparently picked up a small screwdriver — small enough that it couldn’t have caused serious harm, his family says, but enough that they sought law enforcement assistance. Three different police departments’ officers arrived at the scene. The first two were able to restrain Vidal and calm him down, according to Vidal’s father. But then a third entered, and that’s when he says things went sour.

He says the third officer tased Vidal, knocking the 90-pound teenager to the ground. The officer then allegedly stepped forward with a firearm and said, “we don’t have time for this,” before shooting the teen dead.

Southport Police Department, one of the three North Carolina agencies that responded to the call, has put one of its detectives on administrative leave in relation to the case, reports WECT. The department did not say whether the officer was the one who had fired the weapon. The other departments, Boiling Spring Lakes PD and the Brunswick County Sheriff’s office, said that they have not put their responding officers on leave. The State Bureau of Investigation is looking into the incident.

In Durham, police will release a report to the public this week detailing how 17-year-old Jesus Huerta was killed when he was shot in the back of the head while alone and handcuffed in the back of a police cruiser.
